Swarmauri Evaluatorpool Accessibility

Accessibility-focused evaluator pool for Swarmauri programs. The pool bundles a set of classic readability metrics (Automated Readability Index, Coleman–Liau, Flesch–Kincaid Grade, Flesch Reading Ease, and Gunning Fog) and normalises their scores onto a single 0–1 scale where higher values mean easier-to-read content.

Installation

pip

pip install swarmauri_evaluatorpool_accessibility

Poetry

poetry add swarmauri_evaluatorpool_accessibility

uv

# Install into the current environment
uv pip install swarmauri_evaluatorpool_accessibility

# Or add it to the project pyproject.toml
uv add swarmauri_evaluatorpool_accessibility

Usage

AccessibilityEvaluatorPool is a registered EvaluatorPoolBase component. It expects a sequence of Swarmauri Program objects, runs the configured evaluators concurrently, then returns standard EvalResultBase instances with the aggregated score and detailed metadata for every evaluator.

Example

from swarmauri_evaluatorpool_accessibility.AccessibilityEvaluatorPool import AccessibilityEvaluatorPool
from swarmauri_standard.programs.Program import Program

program = Program(content={"example.txt": "This is a simple sentence. Here is another one."})

pool = AccessibilityEvaluatorPool()
pool.initialize()  # spin up the thread pool once before evaluating

results = pool.evaluate([program])
result = results[0]

print(f"Aggregate accessibility score: {result.score:.2f}")
print("Per-evaluator scores:", result.metadata["evaluator_scores"])
flesch_meta = result.metadata["evaluator_metadata"].get(
    "FleschReadingEaseEvaluator", {}
)
print(
    "Flesch interpretation:",
    flesch_meta.get("readability_interpretation", flesch_meta.get("error", "not available")),
)

pool.shutdown()  # release resources when finished

Result structure

Each entry returned from evaluate is an EvalResultBase with:

• score: the weighted mean of the evaluator scores mapped to the 0–1 range.
• metadata["evaluator_scores"]: raw scores keyed by evaluator name.
• metadata["evaluator_metadata"]: evaluator-specific metadata (e.g. sentence counts, syllable estimates, interpretation strings).
• metadata["aggregate_score"]: mirrors .score for convenience.

You can customise the weighting of each evaluator by passing a weights dictionary (name → float) when constructing the pool.

Notes

• The pool automatically registers the bundled evaluators when no explicit list is provided. You can pass your own evaluators that satisfy the IEvaluate interface to override or extend the defaults.
• FleschReadingEaseEvaluator downloads NLTK's punkt tokenizer and cmudict pronunciation dictionary on first use. Set NLTK_DATA_DIR to point to a writable cache location if required. When these resources are not available the evaluator reports an "error" entry in its metadata instead of raising an exception.
